• Fix up various references of 'tint' to 'dawn' post-migration. • Round the CPU speed to 100MHz. This appears to fluctuate on reboots for some machines. • Fix git.Log() - the Count was trimming from the wrong end, leading to perfmon spamming the github repo with repeat results. • Instead of using google-benchmark's `--benchmark_repetitions` flag for repeating benchmarks, calculate averages by re-running the benchmark executable. Use '--benchmark_enable_random_interleaving' to randomize the order in which benchmarks are run, which greatly helps reduce noise in the averaged results. • If the host machine supports CPU temperature sensors, wait for thermals to stabilise before running the benchmarks. Further helps reduce result noise. • Breakout of the historic benchmarking loop every 15 minutes to check for new Gerrit changes to benchmark. • When idle, attempt to re-benchmark historic results that are 'spiky' to reduce noise in the graphs. • Specify more CMake flags to avoid building non-benchmark executables. • Update the default base change for historic results. Attempting to use the old hash, which was prior to the tint -> dawn merge makes, the git log go back to T0 on the dawn branch. We don't want to benchmark nearly 3k changes.
